Caribou
Odyssey III extended, Sonar Survey Autonomous Underwater Vehicle


Caribou is the AUV Lab's newest vehicle. Recently built by Bluefin Robotics Corporation this AUV represents the culmination of significant development efforts. Featuring a modular hull design and the latest evolution of AUV navigation, propulsion and power systems, Caribou provides significant new autonomous survey capabilities and flexibility for other scientific needs.

Equipped with state-of-the-art sensors this AUV can collect high-quality data. Caribou's modular payload sections allow one core vehicle to support widely different science missions. The initial section is designed to accommodate the Edgetech(R) FS-AU side-scan sonar and sub-bottom profiler. Additional payload modules are being designed. The AUV Lab is looking forward to applying Caribou to a wide spectrum of research efforts including: archaeological remote sensing, multi-static acoustic modeling, fisheries resource studies and development of concurrent mapping and localization techniques.
